L. M. Khinchuk and E. A. Preobrazhensky began at the evening session of 
May 26. At the morning session of May 27, these discussions continued, but— 
there is no indication of the names of the speakers who took the floor. 
It is possible that the notes were made sequentially during the course of two 
sessions, since the document in its first part is written in pencil, and in the 
second (beginning with the words: "Chubar: approximately the following one") — in ink. 
In the first part only the words ("and Meshcheryakov") are written in ink. 
In the second part the words "Development of Initiative" are written in pencil 
separate[ly] from the rest of the text.
